The present disclosure relates to a method for verifying a value stream along a transport route, wherein a plurality of field devices, each having at least one sensor and/or actuator for determining and/or monitoring at least one process variable and an electronic unit, are arranged along the transport route and generate corresponding data, or for verifying the value stream of at least one product in warehouse stock, wherein a first service platform is used, via which a plurality of participant nodes each with at least one database have a communication connection to one another according to a distributed ledger or blockchain technology.

Method for verifying a value stream along a transport route or in warehouse stock by means of blockchain technology

The present disclosure relates to a method for starting up or servicing a field device: reading unique identification information assigned to the field device via a static code by means of a reading and/or operating tool; optically reading diagnostic information stored in the field device and which relates to at least one current and/or past event assigned to the field device, via a dynamic code generated by the field device by means of the reading and/or operating tool; transmitting the identification and diagnostic information from the reading and/or operating tool to a cloud-based service platform, transmitting device and/or application-specific information for remedying the event characterized by the diagnostic information from the cloud-based service platform to the reading and/or operating tool, and eliminating the event or effects of the event using the transmitted device-specific and/or application-specific information.

The present disclosure relates to a method for ensuring the authenticity of a field device. The method includes a step of assigning a unique authentic identification feature to the field device or providing the field device with a unique authentic identification feature. The method also includes steps of transmitting ACTUAL identification data to a participant node which transmits the ACTUAL identification data to the other participant nodes in a transaction, validating the transaction by the participant nodes, and creating a data block containing the transaction, wherein the data block is transmitted to each of the participant nodes. The method also includes verifying the data block by all participant nodes, storing the validated data block in the databases, comparing the ACTUAL identification data with corresponding TARGET identification data or original identification data from an authentication point, and generating a response containing the result of the comparison.

Method for ensuring the authenticity of a field device

A measuring device comprising at least two output units for output of measured values, wherein the output units are optically coupled. The optical coupling effects a lessening of the manufacturing effort as well as a galvanic isolation of the output units.

Measuring device of measuring- and automation technology

A laser spectrometer can be operated for analysis of one or more analytes present in a combustible gas mixture. The spectrometer can include one or more features that enable intrinsically safe operation. In other words, electrical, electronic, thermal, and/or optical energy sources can be limited within an hazardous are of the spectrometer where it is possible for an explosive gas mixture to exist. Methods, systems, articles and the like are described.

A housing of a field device of measuring- and automation technology, comprising a housing body, which has at least two housing chambers, wherein the housing chambers are connected together by an opening. The opening is adapted to accommodate a circuit board which is held by at least one holder, wherein the circuit board is adapted to be populated with electronic components or assemblies. The opening is Ex-d sealed with a potting compound.

Housing for a field device

A field device of measuring- and automation technology, which field device meets requirements for operation in explosion-endangered environments. Safe operation of the field device in explosion-endangered environments is assured by a pluggable connector coupling for electrical coupling of different field device components. An essential feature of the pluggable connector coupling is a sealing element for spatial and gas-tight sealing of a contact region of contacting elements of the pluggable connector coupling from a free volume remaining in the pluggable connector coupling.

An electronic device having a housing for accommodating electronic components, preferably electronic components forming a process transmitter. The housing has two chambers, in which electronic components and user interfaces and/or connection elements for cable are arranged. The electronic components are arranged in a first chamber. In the case of a process transmitter, which is simple to maintain, electronic components are arranged exclusively in the first chamber, while user interfaces of the electronic components and/or connection elements for cable are positioned exclusively in the second chamber.

A circuit arrangement comprises a voltage regulator coupled to an external voltage supply and a control loop associated with the voltage regulator. The control loop includes an electrical current controller for setting the electrical current value, an analog-digital converter, a reference resistor and a computation/control unit coupled with the voltage regulator and the said analog-digital converter, and the control loop is so embodied that the voltage regulator, as a function of the presently set electrical current value, controls a voltage to an external load connected with the electrical current output. Particularly the computation/control unit is adapted to calculate a voltage to be delivered by the voltage regulator and to operate both, the electrical current controller and the voltage regulator for setting the electrical current value and to operate and for tuning the voltage delivered by the voltage regulator as a function of the presently set electrical current value, respectively.
